I am a Senior Credentials Coordinator with a Credentials Verification Organization. Basically I run background checks on doctors. I check their medical licenses, work history, professional references, malpractice history, etc. etc. Then, once I gather all the info, I turn it over to our client hospitals and they decide from our file if they want to keep allowing the doctor to treat patients in their hospital. I've been doing this type of work for almost the last 10 years, since I was 16.
